MAMP install confusion

I’ve been running MAMP for some time, but I must have missed something in the wordpress install. When I try to run the install (I did make a config file first), it says it can’t be found at http://localhost:8888/MAMP/wordpress/wp-admin/install.php

If I go to File > Open and locate the file and open file:///Applications/MAMP/wordpress/wp-admin/install.php
I get that it’s already installed with a bunch of weird messages

`’.__(‘Already Installed’).’

‘.__(‘You appear to have already installed WordPress. To reinstall please clear your old database tables first.’).’
‘);} switch($step) { case 0: case 1: // in case people are directly linking to this display_header(); ?>

ReadMe documentation at your leisure. Otherwise, just fill in the information below and you\’ll be on your way to using the most extendable and powerful personal publishing platform in the world.’), ‘../readme.html’); ?>

error) ) wp_die($wpdb->error->get_error_message()); display_header(); // Fill in the data we gathered $weblog_title = isset($_POST[‘weblog_title’]) ? stripslashes($_POST[‘weblog_title’]) : ”; $admin_email = isset($_POST[‘admin_email’]) ? stripslashes($_POST[‘admin_email’]) : ”; $public = isset($_POST[‘blog_public’]) ? (int) $_POST[‘blog_public’] : 0; // check e-mail address if (empty($admin_email)) { // TODO: poka-yoke die(‘

‘.__(“ERROR: you must provide an e-mail address.”).’
‘); } else if (!is_email($admin_email)) { // TODO: poka-yoke die(‘

‘.__(‘ERROR: that isn’t a valid e-mail address. E-mail addresses look like: username@example.com’).’
‘); } $wpdb->show_errors(); $result = wp_install($weblog_title, ‘admin’, $admin_email, $public); extract($result, EXTR_SKIP); ?>

admin

‘.__(‘Note that password carefully! It is a random password that was generated just for you.’).”; ?>`

The two form text fields on the error page aren’t labeled. Ideas on what I’ve screwed up?

Thanks,
